form. Mounted on the top face of the tie are tie plates 3 having 5 whichare arranged to engage with the marginal edges of the rail flanges.Secured upon the seat formed in the tie-plates 3 by the projecting lugsor ribs 4 and 5 are the track rails 6 and as will be clearly seen fromFigs. l and 3, a hole or recess 7, preferably cylindrical is formed inthe top face of the tie and a similar hole 8 is formed in the tie platesso as to register with the recess or hole 7 and be located beneath therail bases when the tie plates and rails are assembled in place on thetie. A metal plug or dowel pin 9 is inserted in the recesses formed bythe holes 7 and 8 so as to prevent any sidewise motion of the tie plateson the top face ofthe ties, or relative to the track rails, the base ofthe rails 6, when placed in position on the tie plate, covering theopenings 7 and plugs 8 and maintaining the pins or plugs 9 in position.Rail clips 10 are employed to secure the rails in position on the ties,the clip bolts ll passing through suitable bolt holes or openings l2 and13 in the tie plate and in the rail clips so as to securely fasten therails in position.

In assembling a track construction employing my improved fastening thetie plates are placed in position on the ties so that the hole 8registers with the openings 7 in the top face of the tie. A dowel pin orplug 9 is then placed in each of these registering openings, the pinsbeing of a length approximating the combined depth of the registeringholes or openings. The track rails are then placed in position on thetop faces of the tie plates, and the clips are secured tothe tie by thebolts 11 extending through the upper face of the ties and the tieplates, in position so as to engage the flanges of and securely hold therails in place. It will be seen that when in such position it isimpossible for the dowel pins 9 to become dislodged and that any sidethrust put upon the rails by rolling stock passing over the track willbe transmitted through the ribs 4 or 5 to the tie plate and, by means ofthe pins 9 to the ties independently of the bolts, and that the boltsare utilized only to maintain the rails and tie plates in position onthe ties of the track construction without at any time subjecting thebolts to shearing strains or stresses.

The advantages of my invention will be apparentto those skilled in theart. By the To all whom it may concern.'

Be it known that I, JOHN F. Lnwis, a citizen of the United States, and aresident of Allegheny and State of Pennsylvania, have invented a new anduseful Rail-Fastening, of which the following is a full, clear, andeXactdescription, reference being had to the accompanying drawings,forming part of this specification.

My invent-ion relates to apparatus used in securing the rails of arailway track in position on the ties and more particularly relates tothe construction of railway tracks employing tie plates and metal tiesto which the rails are fastened when in place.

Heretofore, it has been the practice to depend upon the bolts used forsecuring the rails in place on the ties to take the side thrust on therails caused by sidewise pressure of the rolling stock passing over therails.

The object of my invention is to provide a rail fastening having novelmeans whereby side thrust caused by the sidewise pressure of the rollingstock on the rails is transmitted from the rails through the tie platesto the ties independently of the bolts emloyed in securing the rails inplace on the ties, the necessity of having the bolts in shear when inuse is avoided and overcome and by which the strength of the tiefastening is thereby greatly increased.

Referring to the drawings, Figure l is a side elevation, partly insection, of a metal tie showing my improved means for securing the tieplate and rail in position on the tie. Fig. 2 is an end elevation of thetie showing the rail secured in place thereon. Fig. 3 is a planshowingthe tie plate in position on the tie, and showing the registeringbolt holes and the holes provided in the tie plate and the top face ofthe tie, with the dowel pin placed in position therein in accordancewith my invention. Fig. t is a sectional end elevation on the line IV-IVof Fig. l, showing the recess or opening in the top face of the tie andthe plug or dowel pin by which relative transverse movement of the tieplate and tie is prevented, the railand tie plate being removed for thesake of clearness.

In the accompanying drawings, 2 designates a metal tie of a railwaytrack, the type of tie shown being of general I-beam form, although,obviously, my invention is adaptties of any approved lugs or flanges 4and is obtained, whilel relative sidewise movened in the appendedclaims.

In a railway track construction having a metal tie, a rail fasteningcomprising a tie plate on the tie having a projecting rib engaging theside edge ofthe rail flange, registering openings in the tie plate andtie, a plug loosely seated in said registering openings, registering'bolt holes in the tie plate and tie and rail fastening meansincludingrail clips and clip bolts extending through the bolt holes in the tiesand rail clips for securing the rails in position on the ties.

In testimony whereof, I have hereunto set my hand.

simple expedient of providing registering recesses in the tie plate andtie and inserting a `dowel pin or plug in these openings so as to neatlylill the openings, and by providing lugs or ribs on the top face of thetie plates, which are engaged by the side edges of the rail flanges, theshearing stresses heretofore put upon the bolts by which the rails aresecured to the ties is avoided and a very much stronger fastening mentof the tie plates with respect to the and made practically impossible.

Thetie plates may be bolted to the tie independently of the clip boltsinstead ofutilizing the clip bolts to maintain the tie plate in positionas shown, the form of the clip used may be changed, and othermodifications may be made.
